Abstract:

Beaver Pond Dam is classified as a Significant hazard - Small size dam. The dam was found to be in poor overall condition at the time of inspection. Hydraulichydrologic evaluations, performed in accordance with procedures established by the Baltimore District, Corps of Engineers, for Phase I Inspection Reports, revealed that the spillway will not pass the 100-year flood without overtopping the dam. A spillway design flood SDF in the range of the 100-year flood to the 12 Probable Maximum Flood 12 PMF is required for Beaver Pond Dam. Because the dam is on the low end of the Small size category in terms of storage capacity and height, the 100-year flood was chosen as the SDF. During the 100-year flood, the dam is overtopping by a maximum depth of 3.27 feet for a total duration of 8.67 hours. The spillway is therefore considered Inadequate. It is recommended that the owner immediately develop recommendations for remedial measures to reduce the overtopping potential of the dam.
